## How to call it through Zero

```sh
zero fetch --capability pulsescanner-block-rewards-85c94227
```

Example prompt: What were the fee recipient, gas used, burnt fees, and consensus reward for PulseChain block 21000000?

## When to prefer this

Use this endpoint when you need fee and reward details for a single specific PulseChain block, including the fee recipient, gas consumed, EIP-1559-style burnt fees, and consensus layer reward. Prefer this over the recent-blocks list endpoint when you already know the exact block number and need the full reward breakdown rather than just a summary list.

## Known failure modes

- Block number not yet indexed — returns 404 or empty result if block is ahead of indexed head
- Invalid block number format — non-numeric or missing path param returns 400
- Block number out of range — extremely high or negative values may return an error
- Payment failure — insufficient USDC balance results in 402 payment required
- Network timeout — slow response if the indexer is catching up

## How this service works

One block's fee recipient, gas use and burnt fees, with its consensus reward. PulseChain (chain id 369). $0.003 USDC per call.

## Output

Returns a JSON object containing the block's fee recipient address, gas used, amount of fees burnt, and the consensus (beacon) reward associated with the block on PulseChain (chain ID 369).
